Exchange support on Virtual Server
October 28, 2005, 5:39 pm
Filed under: 1312

Microsoft has reviewed its policy about Exchange support on Virtual Server. Until today Exchange was not supported on Virtual Server, but from now on running Exchange 2003 SP2 on Virtual Server 2005 R2 is officially supported.


More details are at the following KB article:



Remember, you must have SP2 and Virtual Server 2005 R2. By the way, don’t even think in VMware support.

Filed under: News

The Neowin site has just announced that the beta test process for the new Hotmail started today.


The new look will be instantly familiar to anyone who has used Outlook, with message information on the left, and the body of the email being displayed on the right in the reading pane. Along with this new setup, you have the ability to drag and drop emails into different folders, just as you would do in Outlook. You can also right click on emails in the information pane and choose to reply, delete, forward or print. To accompany the fresh new look Microsoft has upped the storage allowance to 2gigabytes.” 


Newowin also provides some screenshots:



Now all I have to do is wait for my invite to come. If you are interested in this beta program you can sign up here.



Configuring SMTP for Both Authenticated and Anonymous Connections
October 24, 2005, 11:16 am
Filed under: 1312

To reduce administrative overhead, the Microsoft Information Technology (Microsoft IT) group needed to change the way Microsoft Exchange Server 2003 makes internal Simple Mail Transfer Protocol (SMTP) connections. Microsoft IT set the SmtpIpRestrictionFlag attribute to 1 to configure an SMTP virtual server to allow anonymous connections from an explicit list of IP addresses, yet allow all authenticated connections from other Exchange servers.

Optimizing Exchange Storage: a real world example
October 18, 2005, 7:21 pm
Filed under: 1312

Exchange storage is a very popular subject nowadays. Sometimes the reason it’s because compliance, other times it’s due to performance reasons. It’s about the latest I’m going to write about.
Exchange storage is such a critical component, that Microsoft thought it deserved a dedicated document with instruction on how to optimize it: Optimizing Storage for Exchange Server 2003. These instructions and guidelines can really make a difference.


To prove it, let me tell you a story:


I have a customer who was dealing with lots of Outlook messages “Outlook is trying to retrieve data from the Microsoft Exchange Server <servername>“.
After a quick analysis of the client’s production environment we concluded that he was having a storage bottleneck.
The next step was to correctly size a new storage configuration that could handle the peak load. The back-end server was an HP ProLiant DL380 G3 with direct attach storage (DAS). After some calculations we concluded that changing the database volume from a RAID 5 to a RAID 0+1 (with just one additional disk) would make the difference.
We also decided to configure write-back cache to that volume. The HP ProLiant DL380 G3 comes with an integrated SmartArray 5i Plus controller. Unfortunately, in order to turn on write-back cache it’s necessary to buy an additional battery. I don’t know if HP has modified its policy on more recent servers, but I strongly think that this battery should come installed on the default server configuration, because it makes such a huge difference.
The client was having an average write latency of 100ms (the recommended value is <20ms). The image below illustrates the original configuration:



After we changed the RAID level to 0+1, we immediately saw performance improvements. The write latency dropped to less than 25ms. Unfortunately I don’t have a performance picture to show you.
But what most impressed us was the effect of the write-back cache. After installing the Battery Backed Write Cache (BBWC) Enabler, write latency dropped even more to a spectacular 3ms. Here’s the picture that proves it:



So, what’s the point with this story?


  • Storage must be sized first for performance and then for capacity;
  • Tuning and write-back cache can really make a difference;
  • You don’t have to buy expensive storage (think SAN) to keep 1.500 users happy.

A 30GB mailbox

Filed under: News

This is not exactly breaking news (Neowin), but I think it deserves to be mentioned in my blog. The site 30Gigs.com is offering mailboxes with 30 GB (!) capacity.


30Gigs.com started off with the idea of creating a “All in one” site for the webmaster and avid computer users. Combining personal file storage, GD2 signatures and anonymous email all in one service, which would be free. Our main goal is to increase our space even further, to 50 gigs, or maybe 100 as time goes on.


The site is still in Beta and the registration only works by invitation. So, does anyone have one for me?



Baseline BIS TCO Assessment – v3
October 13, 2005, 8:43 pm
Filed under: Tools

The Baseline BIS TCO Assessment analyzes a customer’s actual IT costs and helps you to measure the ROI of migrating to Windows Server 2003 and Exchange Server 2003 from NT4, NetWare, Exchange 5.5, and GroupWise. It will only take you about 1 hour to gather information about their IT environment for the tool. The Online Training and a Brand New Project Guide are also available – Training is HIGHLY recommended. This tool is focused on the 50-500 Desktop customer (up to 1000 employees). It is designed to be completed and delivered by a Partner, not the end customer.


I’ve played with the tool a little bit. It gives me a cool report comparing the TCO for the old and new scenarios. The Baseline BIS TCO Assessment – v3 is available here.
